Abstract
Abstract Photoelectrochemical (PEC) oxidation of glucose on bismuth vanadate (BiVO4) electrode for sensor application and solar-to-electricity production was investigated in this work. The BiVO4-based PEC sensor displays a sensitivity of 17.38 μA cm−2 mM−1 for glucose sensing in the concentration range of 5–35 mM. Furthermore, electricity can be collected by extracting solar energy and bioenergy in a certain photo fuel cell (PFC) device via anodic reaction of photo-oxidizing glucose and cathodic reaction of oxygen reduction. This study offers a promising strategy for glucose sensing and provides a cost-effective way for solar-to-electricity generation.
